Re: What's the farthest distance one can go before the Watch loses connection with the iPhone?
How you connect it to the wifi anyway?
From the Apple Watch Manual:
?Apple*Watch uses Bluetooth? wireless technology to connect to its paired iPhone and uses the iPhone for many wireless functions. Apple*Watch can?t configure new Wi-Fi networks on its own, but it can connect to Wi-Fi networks you?ve set up on the paired iPhone.
If your Apple*Watch and iPhone are on the same network but aren?t connected by Bluetooth, you can also do the following on Apple*Watch without iPhone:
Send and receive messages using iMessage
Send and receive Digital Touch messages
Use Siri?

So, you don't have to do anything. The Apple Watch is an extension of your iPhone and connects automatically to any WiFi networks your iPhone is connected to. If you wander around your home or office out of Bluetooth range, you remain connected to the WiFi with your iPhone's credentials. When you return in Bluetooth range, full functionality is restored automatically.
